question about pots

I'm building a P/J bass and I'm wondering what kind of pots I should get. It's my understanding that I will need a 500k one for the P pup and a 250K one for the J.But what about the tone and blend pots?
You can use different pots for different sounds.

IIRC using a 250K pot gives a darker sound than a 500K pot, IIRC that is, it might be the other way round
 
so i could just get 250k pots for everything huh.....cool
Yep. A Fender P-bass calls for a 250K pot, as well as a Fender Jazz bass. Unless the pickup manufacturer's specs call for something different, this is what I would use.

I do repairs and all I keep around is 250K audio taper pots since I mostly own/work on Fenders. Something else comes in, I'll order the parts.
 
In a lot of P-style basses (mine included), it actually uses 500K pots for the tone. I have no idea what the value is on the volume, but that's what I measured on my tone and what others have measured in theirs. I mean, just for comparison, my Peavey with J-style pups uses 250K pots all round.
 
Either 250K or 500K are the usual values - you can look at the schematics on the fender website they give both the pot and cap values for the different fender models

As far as sound goes I like the 250K pot and a 0.047 uF tone cap. The tone circuit is nothing more than a simple low pass filter - given a cap value a 500K pot will attenuate at lower frequencies than the 250K pot.

I have no idea what any of that stuff means but thanks anyway :)
This is the first time I've ever tried to build a bass so as of now I'm just going off of the diagrams that I can find online. I'm sure i'll be back here to ask a lot more questions though
 
b-bottom,

Wherever you buy the kits will probably all be marked for either P-bass of J-bass. If you are really stumped take the bass in to a local tech and they will pull the pieces off the shelf to get you exactly what you need.

Meanwhile...

For a P/J bass you want Volume/Volume/Tone, right? Get a J-bass set, it will have everything you need.

If you want to use a selector switch with one volume and one tone, get a Standard Wiring Kit for Telecaster. (basspartsresource.com)

Want to get wild and do Volume/Volume/Tone/Tone? Get two P-bass kits.
